5、Law 1 If all the forces acting on a particle are balanced, the particle will either remain at rest or will continue to move in a straight line at a uniform velocity.第一定律如果作用在一个质点上的所有外力平衡，那么，这个质点保持原来的静止或者匀速直线运动状态不变。

Lesson 1 Basic Concepts in Mechanics The branch of scientific analysis which deals with motions, time, and forces is called mechanics and is made up of two parts, statics and dynamics. Statics deals with the analysis of stationary systems, i.e., those in which time is not a factor, and dynamics deals with systems which change with time.对运动、时间和作用力进行科学分析的分支称为力学。

它由静力学和动力学两部分组成。

静力学对静止系统进行分析，即在其中不考虑时间这个因素，动力学对随时间而变化的系统进行分析。

Forces are transmitted into machine members through mating surfaces, e. g., from a gear to a shaft or from one gear through meshing teeth to another gear, from a V belt to a pulley, or from a cam to a follower. It is necessary to know the magnitudes of these forces for a variety of reasons. The distribution of the forces at the boundaries or mating surfaces must be reasonable, and their intensities must be within the working limits of the materials composing the surfaces. For example, if the force operating on a journal bearing becomes too high, it will squeeze out the oil film and cause metal－to－metal contact, overheating, and rapid failure of the bearing. If the forces between gear teeth are too large, the oil film may be squeezed out from between them. This could result in flaking and spalling of the metal, noise, rough motion, and eventual failure. In the study of mechanics we are principally interested in determining the magnitude, direction, and location of the forces.力通过接触表面传到机器中的各构件上。

LESSON 1 Classification of Engineering MaterialsNonferrous Metal elements other than iron called nonferrous metals.有色金属元素和像铁一样的有色金属不同。

The nonferrous subgroup includes common lightweight metals such as titanium and beryllium and common heavier metals such as copper, lead, tin and zinc.有色金属包括常用的轻金属，比如钛和铍，还有常见的重金属比如铜，铅，锡和锌。

Among the heavier metals is a group of white metals, including tin, lead, and cadmium; they have lower melting, about 230 to 330.在常用的重金属中，比如锡，铅和镉。

它们的熔点较低，一般是230到330摄氏度。

Among the high temperature nonferrous metals are molybdenum, niobium, tantalum, and tungsten. 高温有色金属包括钼，铌，钽和钨。

Tungsten has the highest melting of all metals: 3400 centigrade. Metal alloys other than iron are called nonferrous alloys are practically endless.钨在所有金属中具有最高的熔点，达到了3400摄氏度。

事实上金属合金远不同于有色金属合金。

Powdered Metals alloying of metals involves melting the main ingredients together so that on cooling, the metal alloy is generally a nonporous solid.粉末合金金属是通过熔化主要金属元素并结合在一起，然后让他们冷却而形成的，金属合金一般是无孔隙固体。
